Kollicoat® SR 30 D is an aqueous dispersion with a solids content of 30%. The low viscosity product has a weak characteristic odour and a milky white or slightly yellowish appearance. The dispersion consists of about 27% polyvinyl acetate, 2.7% povidone and 0.3% sodium lauryl sulfate. It is miscible with water in any ratio while retaining its milky-white appearance. Mixing the product with ethanol or isopropyl alcohol in a 1:5 ratio produces a slightly turbid and somewhat viscous solution; a solution in acetone is more turbid. On addition of further organic solvents the polymer precipitates out but then dissolves when further solvent is added. It is insoluble in dilute alkaline or acidic solutions.
